Check_xi_service_nsclient (USEDDISKSPACE)

[Pselvin]

Hi There,

I am using USEDDISKSPACE argument on check command Check_xi_service_nsclient to check the drive space. Right now I am monitoring drive space using % like this -l C -w 85 -c 95 but, I wanted to use the condition like below,

1. Warning - Generate a warning alert when the drive space goes below 85% and the available space is less than 5 GB.
2. Critical - Generate a critical alert when the drive space goes below 95% and the available space is less than 2 GB.

Thank you in advance!

This documentation may be helpful:
https://docs.nsclient.org/0.5.0/samples/index.html

Specifically, if you wanted to designate multiple criteria for drive space checks, you might give this a shot:

Code: Select all

check_drivesize "crit=free<95% or free<2G" "warn=free<85% or free<5G"

Though I haven't tested that, the syntax works for filters. Unsure if it works for thresholds.

USEDDISKSPACE is checked via check_nt and it does not have those advanced features.

You would need to look at creating a check_nrpe check that allows for more complex options.

First you need to enable NRPE in NSClient++:

This KB article gives an example of an NRPE service:

This page has a list of different disk check commands:

I've not done it myself but I think you can have multiple warning= and critical= arguments, you'll have to test and let us know.

Thank you for your response.

I installed NRPE on the server and it works fine. Please guide me on how to match both condition? I tried all the below but, only one condition works like 10% or the integer value 10gb. Please advise on the parameter to match both conditions

CHECK_NRPE
check_drivesize "crit=free<10%" "crit=free<2G" drive=*:

Do I need to use filter type? if yes, can you guide me on the syntax and how to use in above command

Your command should look like this to get the criteria you are looking for.

Code: Select all

check_drivesize -a drive=C: 'warning=free<5G or free<15%' 'critical=free<2G or free<5%' show-all
